If you're going to spend that initially on speaker cables, I recommend DHLabs.
Also, in a year or two when everything is final and broken in, consider something better. I am using Transparent Ultra Gen 6 on mine. If the tonal balance is perfect and all your components complementary this is a great speaker cable. Speaker cable typically the most important, then the power cord to the amp, and then interconnects and power cords to everything else. But I generally wait a year or so to get into those... you want to know your system inside and out.
